So I'm doing Statistics and it's all good until I got this question:
To answer Part A I did the formula for frequency density (d=f/w where d is f. density, f is frequency and w is class width) to get that the frequency is 10 however the book says 5. Where have I gone wrong?

You are told that there are are 45 households so I'm guessing that you would assume that the total area is equal to 45? Try calculating the total area and see what you get. Please post your thoughts if you're still stuck after this.
